The Vamps - 'Last Night' (Live At The Summertime Ball 2014)

The Vamps made sure their fans had the time of their LIVES when they cracked out this mega-hit during their Capital Summertime Ball 2014 with Vodafone set.

Not sure we've EVER seen four chaps put so much energy into one song, as they raced around the stage amping up the fans and getting them to sing-along with every word.
